In the initial âexpandingâ phase, lymphatic fluid flows at an increased rate and volume from an affected joint to the draining LN via afferent lymphatic vessels. The LN volume expands, presumably to accommodate the influx of cells and lymph exiting the inflamed synovium.
COPD exacerbation. Many people with COPD have attacks called flare-ups or exacerbations (say egg-ZASS-er-BAY-shuns). This is when your usual symptoms quickly get worse and stay worse. A COPD flare-up can be dangerous, and you may have to go to the hospital. Symptoms include: Coughing up more mucus than usual. A change in the color or thickness of that mucus. More shortness of breath than usual. Greater tightness in your chest.
People living with chronic obstructive pulmonary disease (COPD) may have different kinds of symptoms. Some symptoms are early signs of COPD. As the disease progresses, people with COPD may start to have more symptoms. Symptoms may slowly get worse, and start to happen more often. Some symptoms can be signs that a person is having an exacerbation â a COPD attack. Other kinds of symptoms are âsevereâ, because they are signs of very serious problems that need treatment right away.
